A significant fraction of the A-F pulsators show both GDOR and DSCT pulsations (see the examples in Table REF  and in Fig. REF ). Some of them were known prior to space missions [1]}, [2]}. These stars are called hybrids. [3]} found that basically all DSCT stars show low-frequency peaks and are, therefore, hybrids, although some exceptions do exist [4]}. We marked a star as a hybrid when at least two significant peaks (SNR\(>4\) ) with frequencies below and above 5 c/d are present. This is a somewhat weaker criterion than has been used, for example, by [5]} and [6]} who used an amplitude threshold and required that the amplitudes of the peaks in GDOR and DSCT regimes are similar (factor of 5-7). There is a risk that some of the frequencies can actually be a combination of other frequencies [3]}, [8]}. This could lead to a wrong hybrid classification. Further, in rapidly rotating GDOR stars, some of the peaks above 5 c/d can actually be \(g\)  modes shifted to higher frequencies due to rotation [9]}. However, we assume that these issues would be present only in a small fraction of the stars. Because a detailed individual frequency analysis of the data is beyond the scope of this paper, we have not considered these effects in our classification.
